Kraftfahrzeuge werden trotz klimatechnischer Widrigkeiten, wie z.B. Überhitzung der Fahrzeugkabine bei intensiver Sonneneinstrahlung oder Auskühlung gegen den kalten Nachthimmel, mit immer größeren Glasschiebedächern oder Panoramaglasdächern ausgestattet. Der Grund ist das großzügige und freundliche Raumgefühl, das sich für die Insassen in einem hellen lichtdurchfluteten Innenraum ergibt. Konventionelle geschlossene Dachverkleidungen beleuchten den Innenraum nur indirekt durch das Streulicht, das durch die Seitenscheiben in den Innenraum einfällt. Aufgrund des starken Kontrasts zu der hellen Umgebung wirken die konventionellen Dachverkleidungen somit relativ dunkel und für den Fahrer bedrückend.motor vehicles be despite climatic adversities, such. overheating the vehicle cabin in intense sunlight or cooling against the cold night sky, with ever larger glass sliding roofs or Panoramic glass roofs fitted. The reason is the generous and friendly feeling of space for the occupants in a bright light-flooded interior results. Conventional closed roof panels illuminate the interior only indirectly through the stray light, through the side windows falls into the interior. Due to the strong contrast to the bright surroundings the conventional roof panels thus relatively dark and for the driver oppressive.

Diese Aufgabe wird durch den Gegenstand des Patentanspruchs 1 gelöst.These The object is solved by the subject matter of patent claim 1.
Erfindungsgemäß ist der Lichteiter im Bereich der Innenverkleidung des Fahrzeugdachs angeordnet und als flächiger Lichtleiter ausgebildet, wobei die Einkopplung des Lichts an einer oder mehreren Seitenflächen des Lichtleiters erfolgt. Außerdem ist der flächige Lichtleiter derart präpariert ist, dass das Licht aus dem Lichtleiter großflächig und homogen in den Innenraum des Fahrzeugs auskoppelt.According to the invention Light conductor arranged in the region of the inner lining of the vehicle roof and as a surface Formed light guide, wherein the coupling of the light to a or more side surfaces the light guide takes place. Besides that is the areal Prepared light guide in such a way is that the light from the light guide over a large area and homogeneous in the interior decoupled from the vehicle.
Der erfindungsgemäße Lichtleiter dient somit im Gegensatz zu herkömmlichen Lichtquellen, z.B. Glühlampen nicht als Beleuchtungselement, sondern bewirkt eine großflächige und blendfreie Aufhellung der Dachverkleidung im Überkopfbereich der Fahrzeuginsassen. Dadurch schafft der erfindungsgemäße Lichtleiter eine scheinbare Vergrößerung des Innenraums und erzeugt dadurch ein angenehmes Raumgefühl. Der Vorteil hierbei ist, dass durch die homogene Aufhellung des Innenraums durch den erfindungsgemäßen Lichtleiter im Bereich der Dachverkleidung, im weiteren auch als Lichtdach bezeichnet, bei den Fahrzeuginsassen eine psychophysiologisch positive Wirkung erzielt wird.Of the optical fiber according to the invention thus serves in contrast to conventional Light sources, e.g. lightbulbs not as a lighting element, but causes a large area and Glare-free brightening of the roof cladding in the overhead area of the vehicle occupants. As a result, the light guide according to the invention creates an apparent Magnification of the Interior and creates a pleasant sense of space. Of the The advantage here is that the homogeneous brightening of the interior by the light guide according to the invention in the area of the roof cladding, hereinafter also referred to as light roof, in the vehicle occupants a psychophysiological positive effect is achieved.
Ein weiterer Vorteil ist, dass diese positive Wirkung auf die Fahrzeuginsassen nicht nur bei Tageslicht, sondern auch bei Dunkelheit, z.B. Tunnelfahrten oder bei Nacht, erzielt wird. Mittels des erfindungsgemäßen Lichtdachs kann bei Dunkelheit eine blendfreie Aufhellung des Fahrzeuginnenraums erreicht werden, wodurch die Orientierung der Fahrzeuginsassen verbessert wird. Außerdem wird durch das mittels des Lichtdachs geschaffene angenehme Raumgefühl ein aufmerksames und stressfreies Fahren bei Dunkelheit gewährleistet.One Another advantage is that this positive effect on the vehicle occupants not only in daylight but also in the dark, e.g. tunnels or at night. By means of the light roof according to the invention Can in the dark a glare-free brightening of the vehicle interior be reached, thereby improving the orientation of the vehicle occupants becomes. Furthermore becomes attentive by the pleasant feeling of space created by the light roof and ensures stress-free driving in the dark.
Ein weiterer Vorteil des erfindungsgemäßen Lichtdachs ist, dass es als Komponente des Gesamtfahrzeugs eingesetzt werden kann. Außerdem kann das Lichtdach auch als gestalterisches Element im Innenraum des Fahrzeugs genutzt werden.One Another advantage of the light roof according to the invention is that it can be used as a component of the overall vehicle. In addition, that can Lichtdach also as a design element in the interior of the vehicle be used.
Der flächige Lichtleiter ist vorteilhaft ein transparenter Thermoplast, insbesondere Polymethylmethacrylat (PMMA), auch als PlexiglasTM bekannt, oder Polycarbonat (PC). Der Vorteil dieses Materials ist, dass das Material in Form von Platten an die Form gängiger Dachkonstruktionen angepaßt werden kann.The planar light guide is advantageously a transparent thermoplastic, in particular polymethyl methacrylate (PMMA), also known as Plexiglas TM , or polycarbonate (PC). The advantage of this material is that the material in the form of plates can be adapted to the shape of common roof structures.
Die Reichweite, die Farbe und die Intensität des in solchen Lichtleitern transportierten Lichts wird neben dem Absorptionskoeffizienten des Basismaterials, also des eingesetzten Thermoplasten, durch das Aspektverhältnis, dem Verhältnis von Länge zu Dicke oder Durchmesser des Lichtleiters bestimmt. Besonders vorteilhaft weisen die eingesetzten Thermoplasten Materialstärken von 0,1 bis 5 cm, insbesondere 0,3 bis 1,5 cm auf. Zur Auskleidung üblicher Fahrzeugdächer beträgt die Breite der Thermoplasten vorteilhaft zwischen 1 und 3 m.The Range, color and intensity of such light guides transported light is next to the absorption coefficient of the Base material, ie the thermoplastic used by the aspect ratio, the relationship of length determined to thickness or diameter of the light guide. Especially advantageous have the thermoplastics used material thicknesses of 0.1 to 5 cm, in particular 0.3 to 1.5 cm on. For lining usual vehicle roofs is the width the thermoplastic advantageously between 1 and 3 m.
Eine homogene und flächige Auskopplung der in dem Lichtleiter geführten Lichtintensität in den Fahrzeuginnenraum wird durch eine vorteilhafte Strukturierung des Lichtleiters erreicht.A homogeneous and flat Decoupling of the guided in the light guide light intensity in the vehicle interior is achieved by an advantageous structuring of the light guide.
In einer vorteilhaften Ausführung der Erfindung wird die dem Innenraum des Fahrzeugs abgewandte Oberfläche des flächigen Lichtleiters mittels Aufrauung, Prägung oder Bohrung strukturiert. Es ist aber auch möglich, die dem Innenraum zugewandte Oberfläche oder beide Oberflächen zu strukturieren. Besonders geeignet sind hierzu Pyramiden-, Keil- oder Kegelstrukturen mit einer Kantenlänge deutlich größer als die Wellenlänge des sichtbaren Lichts, insbesondere zwischen 1 μm und 3 mm, sowie einem Neigungswinkel zwischen 20° und 70°. Somit ist es möglich, dass das in dem Lichtleiter geführte Licht an den strukturierten Flächen des Lichtleiters abgelenkt und in den Innenraum des Fahrzeugs geleitet wird. Über die Form, die Dichte (Zahl der Strukturen pro Flächeneinheit) und die Tiefe der Oberflächenstrukturen kann die Intensität und die Abstrahlcharakteristik variiert und angepaßt werden. Eine homogene Aufhellung der Dachverkleidung kann insbesondere durch kleine Strukturtiefen und geringer Dichte erreicht werden.In an advantageous embodiment the invention, the vehicle interior facing away from the surface of the flat Optical fiber structured by roughening, embossing or drilling. But it is also possible the interior facing surface or both surfaces too structure. Particularly suitable for this pyramidal, wedge or Cone structures with an edge length significantly larger than the wavelength of visible light, in particular between 1 .mu.m and 3 mm, and an angle of inclination between 20 ° and 70 °. Consequently Is it possible, that guided in the light guide Light on the structured surfaces deflected the light guide and directed into the interior of the vehicle becomes. about the shape, the density (number of structures per unit area) and the depth the surface structures can the intensity and the emission characteristics are varied and adjusted. A homogeneous brightening of the roof lining can in particular by small structure depths and low density can be achieved.
In einer weiteren vorteilhaften Ausführung der Erfindung werden zur Auskopplung des im Lichtleiter geführten Lichts Streuzentren in den Lichtleiter eingebracht. Dabei können die Streuzentren vorteilhaft hoch lichtbrechende Pigmente, z.B. TiO2 oder Lufteinschlüsse mit einer Teilchengröße größer als die Lichtwellenlänge, insbesondere zwischen 1 μm und 3 mm sein. Das in dem Lichtleiter geführte Licht wird an diesen Streuzentren aufgrund der Diskontinuität des Brechungsindex zwischen dem Licht leiter, also dem Thermoplasten, und dem Streuzentrum abgelenkt. Die Streuzentren können auch vorteilhaft als Fasern oder eingefärbte Partikel ausgebildet sein.In a further advantageous embodiment of the invention, scattering centers are introduced into the light guide for coupling out the light guided in the light guide. The scattering centers may advantageously be highly refractive pigments, eg TiO 2 or air inclusions having a particle size greater than the wavelength of light, in particular between 1 μm and 3 mm. The guided in the light guide light is deflected at these scattering centers due to the discontinuity of the refractive index between the light conductor, so the thermoplastic, and the scattering center. The scattering centers can also be advantageously designed as fibers or colored particles.
Die Streuzentren können vorteilhaft aber auch Teilchen sein mit einer Teilchengröße unterhalb der Lichtwellenlänge, insbesondere kleiner als 300 nm. Die Ablenkung des Lichts wird dabei durch Rayleigh-Streuung mit einer isotropen Streuwinkelverteilung bestimmt. Ein Teil des gestreuten Lichts gelangt direkt in den Innenraum des Fahrzeugs. Der in Richtung des Fahrzeugdachs gestreute Teil des Lichts kann vorteilhaft mittels einer zwischen dem Fahrzeugdach und dem Lichtleiter angeordneten und nicht mit dem Lichtleiter in optischem Kotakt stehenden reflektierenden Abdeckung wieder in den Lichtleiter rückreflektiert werden. Es ist selbstverständlich auch möglich, dass Innenverkleidung des Fahrzeugdachs reflektierende Eigenschaften aufweist. Dadurch können Verluste minimiert und der Anteil des Lichts, welcher in Richtung des Fahrzeuginnenraums geleitet wird, erhöht werden.The scattering centers may be advantageous but also particles having a particle size below the wavelength of light, in particular less than 300 nm. The deflection of the light is determined by Rayleigh scattering with an isotropic scattering angle distribution. Part of the scattered light goes directly into the interior of the vehicle. The part of the light scattered in the direction of the vehicle roof can advantageously be reflected back into the light guide by means of a reflective cover arranged between the vehicle roof and the light guide and not in optical contact with the light guide. It is of course also possible that interior trim of the vehicle has bad reflecting properties. As a result, losses can be minimized and the proportion of light, which is conducted in the direction of the vehicle interior, increased.
Es ist aber auch möglich, dass die Streuzentren in dem Lichtleiter eine Kombination aus Streuzentren mit einer Teilchengröße größer als die Lichtwellenlänge und Streuzentren mit einer Teilchengröße kleiner als die Lichtwellenlänge sind. Selbstverständlich können auch Streuzentren in einen Lichtleiter eingebracht werden, dessen Oberfläche strukturiert ist.It but it is also possible the scattering centers in the light guide are a combination of scattering centers with a particle size greater than the wavelength of light and scattering centers having a particle size smaller than the wavelength of light. Of course can Also scattering centers are introduced into a light guide whose surface is structured.
Ein aus allen Blickwinkeln besonders homogenes Erscheinungsbild des erfindungsgemäßen Lichtdachs wird vorteilhaft durch eine auf der dem Innenraum des Fahrzeugs zugewandten Fläche des Lichtleiters zusätzlich angebrachte Streuscheibe erreicht. Die Streuscheibe ist dabei insbesondere derart angeordnet, dass sie nicht in optischen Kontakt mit dem Lichtleiter steht. Diese Streuscheibe wirkt bei Hinterleuchtung durch das erfindungsgemäße Lichtdach als Diffusor, so dass die diskreten Streuzentren oder Oberflächenstrukturen von den Fahrzeuginsassen nicht einzeln aufgelöst werden.One from all points of view particularly homogeneous appearance of the light roof according to the invention will be beneficial by one on the interior of the vehicle facing surface of the light guide additionally reached mounted diffuser. The lens is in particular arranged such that they are not in optical contact with the light guide stands. This diffuser works in backlighting by the light roof according to the invention as a diffuser, allowing the discrete scattering centers or surface structures not be resolved individually by the vehicle occupants.
Das in den Lichterzeugungseinheiten erzeugte Licht wird erfindungsgemäß an einer oder mehreren Seitenflächen des flächigen Lichtleiters eingekoppelt. Das Licht wird dabei mit einem Winkel unterhalb des Grenzwinkels der Totalreflexion in den Licht leiter eingekoppelt. Dadurch wird eine Reflexion an den Seitenflächen des Lichtleiters verhindert. Die Seitenflächen des Lichtleiters, in die kein Licht eingekoppelt wird, können z.B. geschwärzt oder verspiegelt werden. Somit wird das durch den Lichtleiter geleitete Licht an den Seitenflächen absorbiert oder in den Lichtleiter rückreflektiert.The Light generated in the light generating units according to the invention at a or more side surfaces of the plane Fiber optic coupled. The light is at an angle below of the critical angle of total reflection in the light conductor coupled. This prevents reflection on the side surfaces of the light guide. The side surfaces of the light guide, into which no light is coupled, can e.g. blackened or to be mirrored. Thus, the guided through the light guide Light on the side surfaces absorbed or reflected back into the light guide.
Das Licht aus den Lichterzeugungseinheiten ist vorteilhaft über ein Reflektor- und/oder Blendensystem in den flächigen Lichtleiter einkoppelbar. Mittels der Reflektoren und/oder Blenden wird die Abstrahlcharakteristik der Lichterzeugungseinheiten derart angepaßt, dass eine direkte Ausleuchtung des Innenraums durch die Lichterzeugungseinheiten vermieden wird.The Light from the light generating units is advantageous over one Reflector and / or Aperture system in the plane Fiber optics can be coupled in. By means of the reflectors and / or diaphragms the emission characteristic of the light generating units becomes such customized, that a direct illumination of the interior by the light generating units is avoided.
Als Lichterzeugungseinheiten können vorteilhaft ein oder mehrere Leuchtstoffröhren, Leuchtschnüre oder Leuchtdioden verwendet werden. Der Vorteil dieser Lichtquellen ist die niedrige Bautiefe, wodurch ein platzsparender Einbau in das Fahrzeug möglich ist. Die Lichterzeugungseinheiten können z.B. in den seitlichen Längsträgern des Fahrzeugs plaziert werden.When Light generating units can advantageous one or more fluorescent tubes, light cords or LEDs are used. The advantage of these light sources is the low depth, whereby a space-saving installation in the Vehicle possible is. The light generating units may e.g. in the lateral Side members of the Vehicle be placed.
In einer weiteren vorteilhaften Ausführung der Erfindung ist ein elektrischer Regelkreis mit einem Helligkeitssensor vorhanden, welche die in den Innenraum des Fahrzeugs abgestrahlte Lichtintensität an die Umgebungshelligkeit anpassen. Somit wird mit dem erfindungsgemäßen Lichtdach eine adaptive helle Dachverkleidung geschaffen.In A further advantageous embodiment of the invention is a electrical control circuit with a brightness sensor present, which the radiated light intensity in the interior of the vehicle to the Adjust ambient brightness. Thus, with the light roof according to the invention created an adaptive bright roof covering.
In das erfindungsgemäße Lichtdach können die Lichterzeugungseinheiten vorteilhaft in den flächigen Lichtleiter integriert werden. Außerdem ist es möglich, das Reflektor- und/oder Blendensystem in den flächigen Lichtleiter zu integrieren. Der Vorteil ist, dass dadurch eine zusammenhängende Einheit geschaffen werden kann. Somit wird ein kompaktes und mechanisch stabiles Gesamtsystem geschaffen, das auf einfache Weise gefertigt und an beliebig geformte Dachkonstruktionen im Fahrzeug angepaßt werden kann.In the roof of the invention can they Light generating units advantageously integrated into the planar light guide become. Furthermore Is it possible, the reflector and / or Aperture system in the plane Integrate optical fiber. The advantage is that this creates a coherent unit can be created. Thus, a compact and mechanical created a stable overall system, which is easily manufactured and can be adapted to any shaped roof structures in the vehicle.
